What are blackheads? Blackheads are small bumps that appear on your skin due to clogged hair follicles. These bumps are called blackheads because the surface looks dark or black. Blackheads are a mild type of acne that usually form on the face, but they can also appear on the following body parts: back chest neck arms shoulders Acne affects nearly 50 million Americans and is the most common skin disorder in the United States, according to the American Academy of Dermatology. What do blackheads look like? What causes blackheads? Blackheads form when a clog or plug develops in the opening of hair follicles in your skin. Each follicle contains one hair and a sebaceous gland that produces oil. This oil, called sebum, helps keep your skin soft. Dead skin cells and oils collect in the opening to the skin follicle, producing a bump called a comedo. If the skin over the bump stays closed, the bump is called a whitehead. When the skin over the bump opens, exposure to the air causes it to look black and a blackhead forms. Some factors can increase your chances of developing acne and blackheads, including: producing too much body oil the buildup of the Propionibacterium acnes bacteria on the skin irritation of the hair follicles when dead skins cells don’t shed on a regular basis undergoing hormonal changes that cause an increase in oil production during the teen years, during menstruation, or while taking birth control pills taking certain drugs, such as corticosteroids, lithium, or androgens Some people believe that what you eat or drink can affect acne. Dairy products and foods that increase blood sugar levels, such as carbohydrates, may play a part in triggering acne, but researchers aren’t convinced that there’s a strong connection. ADVERTISING What are symptoms of blackheads? Because of their dark color, blackheads are easy to spot on the skin. They’re slightly raised, although they aren’t painful because they aren’t inflamed like pimples. Pimples form when bacteria invade the blockage in the hair follicle, causing redness and inflammation. How are blackheads treated? Over-the-counter (OTC) treatments Many acne medications are available at drug and grocery stores and online without a prescription. These medications are available in cream, gel, and pad form and are put directly on your skin. The drugs contain ingredients such as salicylic acid, benzoyl peroxide, and resorcinol. They work by killing bacteria, drying excess oil, and forcing the skin to shed dead skin cells. Prescription medications If OTC treatment doesn’t improve your acne, your doctor may suggest that you use stronger prescription medications. Medications that contain vitamin A keep plugs from forming in the hair follicles and promote more rapid turnover of skin cells. These medications are applied directly to your skin and can include tretinoin, tazarotene, or adapalene. Your doctor may also prescribe another type of topical medication that contains benzoyl peroxide and antibiotics. If you have pimples or acne cysts in addition to your blackheads, this type of medication may be particularly helpful. Manual removal Dermatologists or specially trained skin care professionals use a special instrument called a round loop extractor to remove the plug causing the blackhead. After a small opening is made in the plug, the doctor applies pressure with the extractor to remove the clog. Microdermabrasion During microdermabrasion, a doctor or skin care professional uses a special instrument that contains a rough surface to sand the top layers of your skin. Sanding the skin removes clogs that cause blackheads. Chemical peels Chemical peels also remove clogs and get rid of the dead skins cells that contribute to blackheads. During a peel, a strong chemical solution is applied to the skin. Over time, the top layers of the skin peel off, revealing smoother skin underneath. Mild peels are available over the counter, while stronger peels are performed by dermatologists or other skincare professionals. Laser and light therapy Laser and light therapies use tiny beams of intense light to decrease oil production or kill bacteria. Both lasers and light beams reach below the surface of the skin to treat blackheads and acne without damaging the top layers of the skin. How can blackheads be prevented? You can prevent blackheads without spending a lot of money by trying a few of the following ideas: Wash regularly Wash your face when you wake up and before you go to bed to remove oil buildup. Washing more than twice each day can irritate your skin and make your acne worse. Use a gentle cleanser that doesn’t make your skin red or irritated. Some acne cleansing products have antibacterial ingredients that kill P. acnes bacteria. Consider washing your hair every day, too, particularly if it’s oily. Hair oils can contribute to clogged pores. It’s also important to wash your face after you eat oily foods such as pizza, because oil from these foods can clog pores. Use oil-free products Any product that contains oil can contribute to new blackheads. Choose oil-free or noncomedogenic makeup, lotions, and sunscreens to avoid making your problem worse. Try an exfoliating product Exfoliating scrubs and masks remove dead skin cells from your face and can help reduce blackheads. Look for products that don’t irritate your skin.

Acute respiratory distress syndrome is characterised by rapid onset dyspnea, bilateral infiltrates on chest x-ray and respiratory failure. This may be due to conditions which directly affect the lung such as pneumonia, aspiration and near drowning. It may also be due to indirect lung injury, as in conditions like sepsis, pancreatitis, trauma and poisoning. The diagnostic criteria of ARDS, often described as the Berlin criteria is discussed in this presentation along with various management aspects of ARDS including ventilation strategies and use of antibiotics and diuretics. Finally prognostic features and alternative strategies are also discussed.

I call this technique deep rendering. I basically stacked graphical cross-sections (in this case, MRI rendering data), using proper increments and clip through them with the camera. This way I am able to explore all internal components in full 3D real-time.

I actually was able to figure out how to colorize different organs to help distinguish them apart from each other but couldn't get the shader to render real-time in Maya.

The ABC's of Adult CPR

The colonoscope is slowly withdrawn during this screening colonoscopy down from the transverse colon, back around the splenic flexure, and down the descending colon, and reveals this finding a colonic diverticula. Diverticulosis is a common, acquired, age-related occurrence affecting over 50% of the... western adult population over the age of 50. It is seen rarely in Africa and Asia where the dietary fiber content is traditionally higher. Thus most investigators feel that low fiber diets are related to the development of this condition. Ironically, colonic diverticula are not true diverticula but rather pseudodiverticula in that the sac includes layers of the mucosa and submucosa that push through rather than include the outer muscular layer. As with the small bowel the colon has an inner circular muscular layer, but the outer longitudinal layer is composed of three bands of muscle that run the length of the colon known as teniae. Diverticula occur in rows between the mesenteric and two antimesenteric teniae where the colonic wall is further weakened by the defect caused by the perforating vasa recti artery which supplies the colonic mucosa. Occasionally, the anatomic propensity of diverticula to form in rows is quite apparent as seen when this clip is replayed in slow motion. Most often, however, the arrangement of the diverticula appears random due to the angulation of the bowel and thickening of the semi lunar folds. The conditions that cause these pulsion diverticula are not know with certainty but may include high intrahaustral pressures, muscular hypertrophy, and age related alterations in collagen cross linking. Diverticula can bleed or can abscess and perforate. The incidence of diverticulitis or diverticular bleeding is in the range of 1:1,000 patients with diverticulosis.

Prostate Cancer spreads in 3 ways. First is spreads by local growth. Second it spreads through the lymphatic system, and lastly, it spreads through the blood stream. Dr. Patrick Swift, a radiation oncologist, discusses how prostate cancer spreads.
